TTElectronics - Welwyn W311R8JI High Power Wirewound Resistor
The W31 Series wirewound resistors are cement coated, flameproof, and custom-built to meet pulse requirements, suitable for industrial and electronic applications. They feature high quality ceramic substrates with welded end caps providing moisture, shock, vibration resistance, and salt spray protection. Terminations are solder-coated copper, meeting IEC standards for strength and solderability. These resistors operate reliably within temperature ranges from -55°C to 155°C, with power ratings of 2.5 watts at 70°C, making them ideal for demanding environments. Available in surface mount Zl-form options, they offer precise resistance values down to 10 milliohms, with temperature coefficients and tolerance as low as 1%. Packaging options include tape and reel or ammo packs, suitable for automated assembly.
